IUBMB Enzyme Nomenclature


Accepted name: farnesoate epoxidase

Reaction: (2E,6E)-farnesoate + [reduced NADPH—hemoprotein reductase] + O2 = juvenile-hormone-III carboxylate + [oxidized NADPH—hemoprotein reductase] + H2O

Glossary: juvenile-hormone-III carboxylate = (2E,6E,10R)-10,11-epoxy-3,7,11-trimethyldodeca-2,6-dienoate

Other name(s): CYP15C1

Systematic name: (2E,6E)-farnesoate,[reduced NADPH—hemoprotein reductase]:oxygen oxidoreductase

Comments: A cytochrome P-450 (heme-thiolate) protein. The enzyme, found in Lepidoptera (moths and butterflies), is specific for farnesoate (cf. EC, methyl farnesoate epoxidase) [1,2]. It is involved in the synthesis of juvenile hormone.
